There is now a clear consensus that the U.S. Federal Reserve will wind down its bond-buying stimulus by the end of next year and will likely hike interest rates late in 2015, a Reuters poll of 62 economists showed on Friday. While most analysts had expected the Fed to wait a few months into next year before announcing it would trim its monthly $85 billion of bond purchases, the fact it did so on Wednesday by $10 billion was welcomed by respondents.
